Ball Screw Selection and Calculations
A ball screw transforms rotational motion into translational motion. As a result, the shaft is subject to loads: Thrust force (the sum of all external forces such as machining load, gravity, friction, inertial forces, etc.). Torque required to generate the thrust force. – Precision Machine Design – Ball Screw Calculations 4-3.
